项目摘要
Siphonophores are a highly diverse group of colonial jellyfish that are widespread and important components of the world’s largest ecosystem, the midwaters of the open ocean. Very little is known about how these jellyfish function. It is thought that the majority of siphonophores spend their entire life suspended in water and move through the ocean via jet propulsion. However, this is likely a gross over-simplification of how this highly diverse group of jellyfish function. The goal of this project is to study how siphonophore shape and body design are related to how they swim, and their swimming and feeding behavior. The main reason so little is understood about these jellyfish, and really most other gelatinous animals in the open ocean, is that scientists have had very limited access to these delicate, remote animals. However, our team has developed tools and techniques that enable our team to study these animals in their natural habitat. In this project, siphonophore swimming movements and mechanics will be quantified using a combination of novel imaging tools controlled by both SCUBA divers and remotely operated vehicles (ROVs). This research will provide an understanding of how the body form of these jellyfish determines how they function. This is critical information for understanding their role in the largest ecosystem of the world. It is also information that can be used by engineers to design better underwater vehicles that move more efficiently and are more maneuverable than current state-of-the-art technology.Siphonophores are colonial cnidarians that are widespread, important components of open ocean communities. It is thought that the majority of siphonophore species spend their entire life suspended in water moving through the ocean via jet propulsion. However, this is likely a gross over-simplification of how this highly diverse group of jellyfish function. The historic obstacle to broader understanding of how these jellyfish function has been the difficulty of accessing these animals. Imaging advances that our team has made in both blue-water SCUBA and with remotely operated vehicles (ROVs) have addressed these limitations. In situ high-speed imaging, bright field, and particle image velocimetry (PIV) for both diver-controlled and ROV operations now allow detailed quantitative measurements of propulsive mechanisms and swimming behavior (short- and long-term) for both surface and deep-dwelling siphonophores. This combination of in situ systems enables our team to collect the multi-scale morphological, kinematic, hydrodynamic, and behavioral data required to be able to establish the benefits and limits of different siphonophore body forms. These results will allow a broad comparison of form and function that is required to understand the trophic role of different siphonophores in the pelagic ecosystem. The results will also contribute to understanding design principles of these colonial species that will inform novel engineered designs that combine jet propulsors in small vehicles, and could ultimately expand exploration and discovery in the oceans. This project will train young scientists, and with the help of our partners, will use video and visualizations for education outreach and engagement of the public.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
管水母是一种高度多样化的群体水母,它们是世界上最大的生态系统的重要组成部分,是开放海洋的中间水域。我们对这些水母的功能知之甚少。据认为,大多数虹吸管水母一生都悬浮在水中,并通过喷气推进在海洋中移动。然而,这可能是对这种高度多样化的水母如何运作的一种过度简化。该项目的目的是研究虹吸管的形状和身体设计与它们的游泳方式以及它们的游泳和摄食行为之间的关系。人们对这些水母,以及海洋中大多数其他胶状动物知之甚少的主要原因是,科学家们接触这些脆弱、偏远的动物的机会非常有限。然而,我们的团队已经开发了工具和技术,使我们的团队能够在这些动物的自然栖息地研究它们。在这个项目中,虹吸管的游泳运动和力学将通过新型成像工具的组合进行量化,这些工具由水肺潜水员和远程操作车辆(rov)控制。这项研究将有助于了解这些水母的身体形态如何决定它们的功能。这是了解它们在世界上最大的生态系统中的作用的关键信息。工程师们也可以利用这些信息来设计出比目前最先进的技术更有效、更机动的更好的水下航行器。管水母是一种广泛分布的群体刺胞动物,是开放海洋群落的重要组成部分。据认为,大多数虹吸水母一生都悬浮在水中,通过喷气推进在海洋中移动。然而,这可能是对这种高度多样化的水母如何运作的一种过度简化。要更广泛地了解这些水母的功能,历史上的障碍一直是难以接近这些动物。我们的团队在蓝水潜水和远程操作车辆(rov)方面取得的成像进步解决了这些限制。用于潜水员控制和ROV操作的原位高速成像、亮场和粒子图像测速技术(PIV)现在可以对水面和深海虹吸管的推进机制和游泳行为(短期和长期)进行详细的定量测量。这种原位系统的组合使我们的团队能够收集多尺度形态学、运动学、流体动力学和行为数据,从而能够确定不同虹吸体形式的优点和局限性。这些结果将允许对形式和功能进行广泛的比较,这是了解不同虹吸管在远洋生态系统中的营养作用所必需的。这些结果也将有助于理解这些殖民地物种的设计原则,这将为在小型车辆中结合喷气推进器的新型工程设计提供信息,并最终扩大海洋的探索和发现。该项目将培训年轻科学家,并在我们合作伙伴的帮助下,利用视频和可视化技术进行教育推广和公众参与。该奖项反映了美国国家科学基金会的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
